.SH NAME
libssh2_sftp_statvfs, libssh2_sftp_fstatvfs - get file system statistics
.SH SYNOPSIS
.nf
#include <libssh2.h>
#include <libssh2_sftp.h>

int
libssh2_sftp_statvfs(LIBSSH2_SFTP *sftp, const char *path,
                     size_t path_len, LIBSSH2_SFTP_STATVFS *st);

int
libssh2_sftp_fstatvfs(LIBSSH2_SFTP_HANDLE *handle,
                      LIBSSH2_SFTP_STATVFS *st)
.fi
.SH DESCRIPTION
These functions provide statvfs(2)-like operations and require
statvfs@openssh.com and fstatvfs@openssh.com extension support on the server.

\fIsftp\fP - SFTP instance as returned by
.BR libssh2_sftp_init(3)

\fIhandle\fP - SFTP File Handle as returned by
.BR libssh2_sftp_open_ex(3)

\fIpath\fP - full path of any file within the mounted file system.

\fIpath_len\fP - length of the full path.

\fIst\fP - Pointer to a LIBSSH2_SFTP_STATVFS structure to place file system
statistics into.
.SH DATA TYPES
LIBSSH2_SFTP_STATVFS is a typedefed struct that is defined as below

.nf
struct _LIBSSH2_SFTP_STATVFS {
    libssh2_uint64_t  f_bsize;    /* file system block size */
    libssh2_uint64_t  f_frsize;   /* fragment size */
    libssh2_uint64_t  f_blocks;   /* size of fs in f_frsize units */
    libssh2_uint64_t  f_bfree;    /* # free blocks */
    libssh2_uint64_t  f_bavail;   /* # free blocks for non-root */
    libssh2_uint64_t  f_files;    /* # inodes */
    libssh2_uint64_t  f_ffree;    /* # free inodes */
    libssh2_uint64_t  f_favail;   /* # free inodes for non-root */
    libssh2_uint64_t  f_fsid;     /* file system ID */
    libssh2_uint64_t  f_flag;     /* mount flags */
    libssh2_uint64_t  f_namemax;  /* maximum filename length */
};
.fi

It is unspecified whether all members of the returned struct have meaningful
values on all file systems.

The field \fIf_flag\fP is a bit mask. Bits are defined as follows:
.IP LIBSSH2_SFTP_ST_RDONLY
Read-only file system.
.IP LIBSSH2_SFTP_ST_NOSUID
Set-user-ID/set-group-ID bits are ignored by \fBexec\fP(3).
.SH RETURN VALUE
Returns 0 on success or negative on failure. If used in non-blocking mode, it
returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
.SH ERRORS
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.

\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.

\fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -

\fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
received on the socket, or an SFTP operation caused an errorcode to be returned
by the server.
